Specification of Letters Patent.

Application filed April 15, 1913. Serial No. 761,249.

To all whom it may concern Be it known that T, CALVIN H. BILLINGS- LEY, a citizen of the United States, residing at French Lick, county of Orange, and State of Indiana, have invented certain new and useful Improvements in F eed-Water Heaters, of which the following is a specification.

This invention relates to feed water heaters.

The present invention relates to those feed water heaters, particularly for locomotive boilers, which are heated by the direct contact of flame and products of combustion and are located in the smoke-box of the locomotive or other boiler.

My object is to provide an improved feed water heater which. will occupy the same space now occupied by the usual deflector plate and will serve as a substitute therefor in addition to serving as a reservoir for heating the feed Water, without interfering with freedom of the draft of the boiler and which will occupy practically no more space than the ordinary deflector plate and can be installed in the boiler at small expense.

The invention serves as a combined deflector plate, draft sheet and feed water heater and, without detracting from the freedom of draft or steaming qualities of the boiler, serves as a direct-heated reservoir by which the water is heated to nearly the temperature of the boiler water before it enters the latter; the invention has the further advan tage that it does not interfere with free access to the smoke-box.

The invention consists, first, in the provision of a combined imperforate deflector, draft sheet and feed water heater; second, in the provision of an imperforate feed water heater of particular form and construction and, third, in the feed water heater of particular form and construction dis posed in front of the flues and extending across the smoke-box and serving as a combined imperforate deflector plate, draft sheet and feed water heater.

In the accompanying drawings: Figure 1 is a plan view of the invention prior to its connection to the smoke-box; Fig. 2, a verti cal section; Fig. 3, a side elevation, partly in section, showing the invention in position in the smoke-box of a locomotive; Fig. l, a front view of the device alone; and Fig. 5, a front view looking toward the invention when in position in a locomotive smoke-box.

Referring first to Figs. 1, 2 and 4, A is the imperforate inclined front and H the parallel imperforate inclined back of the feed water heater, the upper horizontal part thereof being shown at B and the lower horizontal part at C. The front and back are connected by stay bolts F. The upper and lower horizontal parts are connected by rivets G. At the front there are provided clean-out holes having plug closures I and the central part of the front is provided with a recess to cause it to straddle the nozzle box J. The sides have flanges provided with holes K through which bolts may be passed to connect the device to the boiler shell, the arrangement being such that when the feed water heater is in position, it extends completely across the boiler shell and causes all of the flame and products of combustion issuing from the flues O to be deflected, after striking the rear part H, and to pass under the front part of the ordinary draft sheet P into the smoke-box L. As usual, a screen or netting L is provided to retain sparks. The inlet pipes for the feed water heater are shown at D and D and the outlet pipesat E, E, the former being connected with the injector of the locomotive and the latter to the boiler.

N, N represent the ordinary steam pipes leading to the cylinders, not shown, and L L are the usual lift pipes, while M is the smoke stack.

P is the usual blower pipe.

The plates A and H are preferably constructed of boiler; plate and the complete feed water heater shown in Figs. 1 and 4 is shaped and made of any desired size to fit the smoke-box.

The feed water entering through pipes D, D, is spread as a relatively thin sheet between the plates A and H, and consequently, the flame and products of combustion issuing from the flues 0 when striking the feed water heater, quickly raise the temperature of the water contained therein almost to steam heat so that the feed water is injected into the boiler at a very little lower temperature than that of the boiler water, and

no additional consumption of coal or extra labor is required. At the same time, the feed water heater serves as a combined deflector and draft sheet and aids the draft as does the usual draft sheet whose place it takes.

lVhenever necessary, the plugs I are removed and the sediment in the heater allowed to escape into the smoke-box, from which it can be removed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

The combination with the flues, smokeboX, usual draft sheet and nozzle-box at the forward end of a locomotive boiler, of a combined deflector, draft sheet and feed water heater independent of the usual draft sheet aforesaid, consisting of a substantially thin and flat reservoir having imperforate upright and horizontal parts, the walls of which are connected by stay bolts, said upright and horizontal parts being arranged at an angle to each other and both extending entirely across the smoke-box and connected to the interior of the boiler shell, said feed water heater being disposed with its upright part constituting a deflector which is inclined downwardly and forwardly in relation to the front end of the boiler and disposed in front of the fiues thereof, the horizontal part of the reservoir being also hollow and straddling said nozzle-box and provided with clean-out means at its front, the feed Water heater being adapted to directly receive the flame and heat from the boiler fiues and to deflect them below its lower edge and below the horizontal part aforesaid, and water inlet and outlet means for said reservoir.

In testimony whereof, I hereunto afiix my signature in presence of two witnesses.
